feed and weed type weedkillers tend to work on what they call broadleafed plants. chives are not broadleafed. The only thing I can suggest is that you dig out small pieces at a time. remember they have a small bulb to remove too.

That is so strange Mistlass. Chives took my small border until last autumn, but never transferred to the lawn, as some other plants have done. I had a blitz on them. Left a few in place for kitchen use. Is cutting the grass not able to keep them to an acceptable level? Grape Hyacinths won't do a thing in my garden Bryony. Tried so many times to get them going. There is one group of them where I never planted them! I have also had an invasive onion smell bulb that Bulbaholic said might be very invasive Stinking Willie! All over one end of my wide border....never went on the lawn. Blitzing them too this spring. A photo would help to identify. Try googling our friend Willie it might fit the bill!

I haven't had any chives that have spread either,but I do cut the flowers off,when getting past their best,so they don't seed.I have just split my large clump,and haven't seen any growing anywhere else.Maybe as suggested by the above members,it could be something else....

Whatever you have in your lawn, be it chives or garlic and other weeds, those that are monicotes like grass and are growing taller than the grass, can be damaged by your mower on a high cut. By applying Verdone it will enter the cuts going to the bulbs or roots. Also any dicotes will be killed as well. Do not apply in dry weather as we in Surrey are in our second drought. No rain the first two weeks in March and now none in April.
